The European Patent Office (EPO) has granted AS a European Patent for its innovative fan cowl door designed for commercial aircraft nacelles. This advanced solution introduces a fireproof composite structure that redefines safety, performance, and efficiency in engine nacelle design.
Unlike traditional metallic cowl doors that require thermal blankets and are prone to component detachment in case of fire, the AS design integrates fire resistance directly into the structure, eliminating the need for additional insulation layers. This approach not only enhances safety during fire events but also reduces the risk of debris detachment, which could endanger the aircraft.
Furthermore, the use of advanced composite materials makes the fan cowl door significantly lighter, contributing to improved aircraft efficiency and lower fuel consumption. The solution is also easier to manufacture and maintain, reducing operational costs for airlines.
This patent underscores AS’s commitment to delivering next-generation aerospace technologies that combine safety, sustainability, and performance.
